Molar mass of CoCl2 is 129.8392 g/mol Compound name is phosgene Convert between CoCl2 weight and moles The molar mass of water in the compound = 6 x 18.01 = 108.06 % of water = Molar mass of water / molar mass of compound x 100 The drug is a small organic compound with a molecular weight of about 140 g/mol.

## Is CoCl2 a hydrate?

A hydrate is a compound that has one or more water molecules bound to each formula unit. Ionic compounds that contain a transition metal are often highly colored. The name of the compound is cobalt (II) chloride hexahydrate and its formula is CoCl2 •6H2O.

## How do you find the percent of water in a hydrate?

Divide the mass of the water lost by the mass of hydrate and multiply by 100. The theoretical (actual) percent hydration ( percent water ) can be calculated from the formula of the hydrate by dividing the mass of water in one mole of the hydrate by the molar mass of the hydrate and multiplying by 100.

## What is hydrate formula?

Formula of a Hydrate (Anhydrous Solid⋅xH2O) In order to determine the formula of the hydrate, [Anhydrous Solid⋅xH2O], the number of moles of water per mole of anhydrous solid (x) will be calculated by dividing the number of moles of water by the number of moles of the anhydrous solid ( Equation 2.12.

## Is the dehydration and hydration of CoCl2 reversible?

So, to answer your question, the dehydration and hydration of cobalt(II) chloride are reversible because by adding water to the anhydrous form you can reform the hexahydrate. You drive off the water of hydration upon heating to get the anhydrous salt, then add water to the anhydrous salt to reform the hexahydrate.

## Is CoCl2 6H2O Efflorescent?

This number is stated in the formula of the hydrate, as in the formulas CuSO4•5H2O or CoCl2 • 6H2O. A few hydrated compounds lose water spontaneously to the atmosphere upon standing. Such compounds are called efflorescent. All hydrated compounds may be dehydrated by heating.

## What is the percentage of water in the hydrate CoCl2 6H2O quizlet?

You’ll get 52.17%.

## Why is CoCl2 pink?

Cobalt chloride, CoCl2, is a fascinating compound that changes color in response to humidity. As humidity increases, cobalt chloride changes color from sky blue to purple to pink.

## What happens when CoCl2 is dissolved in water?

CoCl2 (aq) —–> Co+2 (aq) + 2Cl- (aq) 0 1. 6 matches found for CoCl2, 6H2O. 6H2O to water, it dissolves to give Chloride ions and CobaltII ions in solution.

## How can you make sure that all of the water of hydration is removed?

A hot plate is used for heating the hydrate in a crucible at least 2 times for 10-15 minutes at medium-high setting. How can you make sure that all the water of hydration is removed? Perform a heating, cooling, weighing cycle until duplicate masses are obtained between weighing cycles.

## What happens if you overheat a hydrate?

Overheating the hydrate can decompose the anhydrous compound, which gives high results.

## How do you calculate the percentage of water in your body?

The easy way to calculate total body water is simply to multiply 0.6 times your weight in kilograms, since roughly 2/3 of your body weight is water. There are fancier (and more accurate) equation -based calculations used to determine total body water as well.

## What is the mass of water in the hydrate?

The mass of water in the hydrate is the coefficient (6) multiplied by the molar mass of H2O. The molar mass of the hydrate is the molar mass of the CoCl2 plus the mass of water.
